Abstract (en)
[origin: EP1840888A1] A method for restoring data stored along a data storage path on an optical disc which is unreadable for conventional optical disc drives due to undesired chemical or physical changes within a recording layer of the optical disc comprises the following steps: - detecting deformations (14) of a groove (6) extending along the data storage path, the deformations (14) being generated by a laser beam during a recording process, - determining the data to be restored from the detected deformations (14) and lands (8').
